Creating volume¶
In general list of all volumes on control panel open volume creation wizard clicking «Create volume»:
In window that opens, indicate:
- Volume name is an optional field, if the value is empty, the name is generated automatically;
- Description is optional field;
- Volume source, select the type of boot source;
- Type, select of a ready-made volume template. Type editing is described in the «Volume types» tab;
- Size is the amount of volume storage in gibibytes;
- Availability zone, choice is made based on the need for certain resources;
- Group, select group to which the created volume will belong;
- «Thin Volume» Flag, when choosing flag, «Thin provisioning» technology is used, which allows to use the free volume space for other needs of project.
Follow the directions, choosing options based on amount of resources available. We complete creation procedure with the «Create volume» button. After that, the correctly created volume will be displayed in the general list. Otherwise, the system will return you to the wizard window indicating the reasons for the impossibility of its creation.
After the successful creation procedure is completed, the volume may take time to finalize all systems. Ultimately, volume is displayed with the status «Active».
Volume image creating¶
This function allows to load volume to image service as an image. It is available in general list. After calling the action in the window that opens, set the name and format of the image.
Created image is displayed in the tab “Images” with the “Active” status.
Volume snapshot creating¶
Action is available in the general list. After calling the action, you will be prompted to specify the name and description of the snapshot; the fields are optional. If the value is empty, the name will be generated automatically.
Confirm the snapshot creation, after which the snapshot will be displayed in the tab “Volume snapshots” with the “Available” status.
Volume backup creating¶
Action is available in the general list. After calling the action, you will be prompted to specify the name and description of the backup; the fields are optional. If the value is empty, the name will be generated automatically.
Confirm the backup creation, after which the backup will be displayed in the tab “Volume backups” with the “Available” status.
Launching instance from volume¶
Function is available in the general list. It allows to create instance using the selected volume. The creation procedure is described in more detail on the page “Launching instance”.
Migration LV¶
Function provides the ability to migrate data for alogical volume on active system from current physical volume to selected one. This function is available in individual volume actions. Select the required volume and call “Migrate LV”:
Select physical volume from the list of available ones for transfer and click «Migrate LV».
Important
Specifying the physical volume to transfer is optional. In this case, the transfer will be carried out to the automatically selected.
Convertation to mirrored volume¶
Note
Action is not available for volumes with the «Thin Volume» flag.
Function allows to convert standard volume to mirrored one. Mirroring technology allows to protect data in the event of a possible failure of physical disk, by saving multiple copies of files. This type is useful for protecting sensitive data in the event of possible hardware failures. This function is available in individual volume actions. Select the required volume and call “Make mirrored volume” action:
After confirmation, the volume will be converted to mirrored. You can see the type of logical volume on the page with detailed information, in the tab “Overview”.
Convertation to standard volume¶
Note
Action is not available for volumes with the «Thin Volume» flag.
Function allows to convert mirrored volume to standard one. This function is available in individual volume actions. Select the required volume and call “Make standard volume” action:
After confirmation, the volume will be converted to standard. You can see the type of logical volume on the page with detailed information, in the tab «Overview».
Changing volume type¶
Function allows to edit type and migration policy of the selected volume. It is available in the general list of all volumes. After calling the action in the window that opens, set the necessary parameters:
End the procedure with the confirmation button.
Volume extending¶
Function allows to resize the selected volume within the allocated project quota. You can resize both a volume that is not attached to the instance with the “Available” status, and a attached one with “In-use” status. After calling the action in the window that opens, set the required size:
End the procedure with the confirmation button.
Volume transfer start¶
Volume can be transferred from one project to another. The function is available in the general list of all volumes. After calling the action, you will be prompted to set the name of the volume transfer, the field is not required to be filled in, and if the value is empty, it will be generated automatically.
Then you need to save the ID and authorization key of created transfer:
End the procedure with the confirmation button.
Volume transfer acceptance¶
Note
It is possible to accept the transfer of the volume only if the ID and the authorization key of the previously created transfer are available.
Function is available on the control panel in the general list of all volumes. After calling the action in the opened window, specify unique data:
Such as:
- Transfer ID;
- Authorization key.
You can also load the volume transfer credentials from the file obtained during the transfer creation step. We finish the procedure with the confirmation button. Then the volume will be displayed in the general list. Otherwise, the system will return you to the wizard window indicating the reasons for the impossibility of accepting the transfer of the volume.
Volumes attachment management¶
Function is available in the general list of all volumes. If there are instances in the project, it allows you to control the attachment of the selected volume to the instance:
You can select available instance in the list by one of the parameters:
- Name;
- IP address;
- Type;
- Status;
- Zone;
- Direct SCSI.
Note
When attaching volume to the instance with Direct SCSI sending SCSI commands to the volume will be done directly, bypassing the hypervisor.
Sorting and filtering tools are implemented for each of parameters. It is also possible to sort the objects marked with check mark.
Also, depending on volume type, it is possible to connect the volume to multiple instances. The multi-mount volume type setting is described in the Administrator/Block Storage Resources/Volume Types section.
The required instance is attached using button «↑». To detach instance use «↓». End the procedure with the confirmation button.
Scheduling actions on volume¶
Select the required volume and call the action:
In the wizard window that opens, select the date. Highlighted days indicate the presence of planned actions on this object for the date, and blue marks indicate their number.
To go to the next step in the field of the selected date, click on an empty area or number. In the first case, you will be redirected to the task creation window. When you click on the number, you will be immediately prompted to select the duration:
